쇼케이스에서 고온가스바이패스 제상사이클의 성능에 관한 실험적 연구

During the defrosting process, the temperature in the cabinet of a showcase becomes high above the setting point, which is not desirable for stored foods or materials. It is necessary to develop a more efficient defrosting method to prevent large temperature fluctuation. In this study, the performance of a showcase refrigeration system with three evaporators is investigated by applying a hot-gas bypass defrosting technology in the system under frosting and defrosting conditions. As a result, the hot-gas bypass defrosting method shows a higher refrigerating capacity and a stable operation condition.
